Doctor Who - The Companion Chronicles: Project: Nirvana is the latest in Cavan Scott and Mark Wright's 'project' series of tales, which traditionally deal with the sinister secret organisation known as The Forge. In this latest tale, former Forge operative Lysandra Aristedes and Private Sally Morgan take a trip into the past on the Doctor's orders and learn some surprising things...

Project: Nirvana stars Maggie O'Neill as Aristedes and Amy Pemberton as Sally, with special guest Sylvester McCoy as the Doctor (who he played on screen between 1987 and 1996). It's available for download now, and CDs will be mailed out today.
